Strain Description:

Emerald Jack is a bold, flavour-forward hybrid that shines in both effect and growth. The Jack Herer lineage brings mental clarity, creative energy, and an uplifting cerebral buzz, while Emerald OG adds body balance, tangy depth, and enhanced potency. The resulting strain provides a euphoric, clear-headed high that’s perfect for daytime use, brainstorming, or social settings. It’s stimulating without being overwhelming, finishing with a gentle Indica calm that softens the edges of its energetic Sativa drive.


The plant grows rapidly, showcasing long internodes and impressive height, producing elongated, trichome-laden colas with a distinct tropical and citrus scent. With proper care, Emerald Jack delivers a strong yield of fragrant, sticky buds that delight the senses and elevate the mood.


Growing Information:

Emerald Jack thrives in environments where it has room to stretch—expect it to double in height during flowering. Early training, topping, or SCROG methods are highly recommended for indoor cultivation to maintain canopy control. It’s a nutrient-hungry strain that benefits from steady feeding of nitrogen, calcium, and magnesium during its vigorous vegetative phase.


The buds develop dense, resin-rich clusters that may require staking or trellising to support their weight. Flowering completes in 9–10 weeks indoors, and outdoor growers can expect harvests by mid-October. While it demands attention to space and nutrients, Emerald Jack rewards growers with premium, aromatic yields that stand out for both quality and character.


Flavour and Aromas:

Emerald Jack’s flavour profile is an explosion of tropical and citrus notes, layered with tangy and sour accents. The aroma is a refreshing blend of sweet fruit, lemon zest, and light herbal spice. On the palate, it delivers a fruit salad-like medley with hints of pine and a crisp, sour finish. Dominant terpenes include terpinolene (fruity, floral, and energising), limonene (citrus and uplifting), and pinene (clear-headed and refreshing), giving the strain its bright aroma and mental focus.


Strain Lineage:

Jack Herer: A globally celebrated Sativa hybrid known for its euphoric energy, clarity, and citrus-forward aroma.

Emerald OG: Adds depth with earthy, tangy citrus flavours, improved structure, and an extra layer of potency.


Together, they form a flavour-rich, high-performing hybrid that delivers stimulating effects and lush tropical character.


Effects:

The effects of Emerald Jack are immediate and uplifting, providing an energetic cerebral buzz that enhances creativity, focus, and mood. It’s ideal for daytime use, artistic work, or socialising, offering long-lasting euphoria without anxiety or overstimulation. As the high settles, a gentle Indica body ease rounds out the experience, leaving you refreshed and content rather than sedated.
